Application filed April 3, 1908. Serial No. 42%,945.

To all whom it may concern:

Be it known that I, Ennnn'r N. SIPPEBLEY, of South Norwalk, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Vibratory "lassage Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide a simple and highly efficient vibratory massage apparatus wherein the force of the vibration may be readily varied without the necessity of adjusting any of theparts.

Briefly stated, the invention resides in so constructing and arranging the parts as to enable the vibratory force to be controlled wholly by the speed of actuation.

The invention will be hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation, with parts broken away. Fig. 2 is a view at right angles to Fig. 1, with parts in section. 3 is a plan view with the top of the housing removed.

Referring to the drawings, 1 designates the casing wherein is located the ordinary operating gearing (not shown) 2 the handle secured at one end to the casing; 3 a tubular extension of the casing; i a circular housing on the end of the tubular extension; 5 the crank handle for operating the gearing; and 6 the rotary shaft which extends from the gearing through the tubular extension into the circular housing.

7 designates an arm which is held by a thumb screw 8 against a seat formed by a collar or enlargement on shaft 6. To the outer bifurcated end of this arm is pivotally connected a second arm 9. This second arm is normally ield at right angles to the arm 7 by a coiled spring 10, a wall 12 formed by bifurcating the outer end of arm 7 serving as a stop to limit the movement of arm 9 under the influence of spring 10. This arm 9 at its free end carries a roller 13 which, in the operation of the device, contacts with a series of spacedapart inwardly projecting abutments 1 1 preferably formed with a ring 15 secured to the inner side of the circular housing 41. The abutments, and the ring itself, are usually made of rubber or other fibrous substance.

It is obvious that in lieu of the roller 13 the end of arm 8 may be rounded.

it will be apparent that as the shaft 6 is rotated, carrying with it the arm 7, the second arm 9 will, by centrifugal action, swing outwardly as against the tension of the spring 9 and in its revolutions will contact with the several abutments 1 1-, the intermittent engagement with the abutments imparting a vibratory motion to the device.

A semi-spheroidal sheel 16 is detachably secured on the circular housing so as to inclose and conceal the vibratory mechanism. This shell may be of any suitable material, and if of metal may be covered with rubber or other soft substance. if desired a cup 17 may be detachably secured to one side of the circular housing.

The advantages of my invention will be apparent. It will be seen that in order to increase or decrease the force of the vibratory motion, it is not necessary, as has heretofore been customary, to readjust any of the parts, the action of the device being always wholly under the control of the o1 erator.

I claim as my invention:

1. In a massage apparatus having a rotary operating shaft, an arm carried by said shaft designed to swing outwardly under centrifugal action, a housing inclosing such arm, and a series of spaced-apart abutments within the housing with which said is designed to engage for effecting a vibratory motion, the force of such motion being controlled by the speed at which the shaft is actuated.

2. In a massage apparatus having a rotary operating shaft, a swinging arm carried by said shaft, a housing inclosing said arm, a series of abutments within said housing with which the free end of said arm is designed to engage under centrifugal action, and means tending to hold said arm out or" engagement with said abutments.

3. In a massage apparatus having a rotary operating shaft, an arm mounted 011 said shaft, a second arm pivoted at one end to the first mentioned arm, ahousing in closing said arms, a series of spaced apart abutments within said housing with which the free end of said second arm is designed to engage when said arm is swung outwardly under centrifugal action, and means tending to hold said second arm as against such outward movement.

4. Ina massage apparatus having a rotary operating shaft, an arm carried on said shaft, a second arm pivoted to the first mentioned arm, a stop on said first mentioned arm, a spring for normally holding said second mentioned arm against said stop, a housing inclos'ing said arms, and a series of spaced apart abutments within said housing with which the free end of said second mentioned arm is designed to engage by centrifugal action as against the tension of said spring.

5. In a massage apparatus having a rotary shaft, a pivoted arm carried thereby,

(means for normally elding said arm from 15 swinging outward under centrifugal action, a housing inclosing said arm, and a ring within said housing having, a series 7 of spaced-apart abutments with which the free end of said arm is designed to engage under centrifugal action.

In testimony whereof, I have signed this specification in the presence of two sub-' scribing witnesses.
